Contact lenses have long been a godsend for people who want to ditch their glasses, and now a new, color-changing type of lens could make life a thousand times easier for diabetics. Up until recently, most diabetics have no choice but to rely on e-waste-generating, finger-pricking meters to get accurate readings of their blood-glucose levels. However a biochemical engineer at the University of Western Ontario has developed moodring-like contact lenses that turn different colors to indicate changes in glucose levels. The new lenses stand to make the once painful daily ritual as simple as opening your eyes.
This is good news for pain fearing diabetics out there. This color changing contact lenses is both cool and useful for the medical industry.
